MACHINE FOR APPLYI'NG CAPs To BOTTLES.

To all 'whom t may concern: l'

Be it. known that I, FREDERICK RECHT, a

. for Applying Caps to Bottles,A of which the i: Afollowing is aspecification.

This invention is intended particularly for the application 'tot-hemou'tzhs of bott-lcs of metallic sealing caps which are providedwith a coijnpre-ssible or elastic sealing medium, as disks of cork` andmeans for locking the caps to the hotties. Such caps can, I

find', be most satisfactorily applied by means of a capping-headcontaining. a -chuck constructed to receive the caps and t.ln ough whichpressure is applied in the direction of the bottle-axis by relativemovement. of the capping-head and the means hy which the bottle is heldduring theclosire. Such a chuck is set forth` in Letters Patent of theUnited States granted to me July 2T,

1909, No. 929.248. The requisite axial pressure is considerable, `and asthe power expendedv is proportionate .to the distance through whichthe.Y moving parts fare 11i:- quired to tra-vel while the pressure issus; tained. it is desirable that such movement he reduced as much aspossible by proper zuliustment. CloseA positive adjustment to reducesuch movement has not been possible in bottle-cappingr machines as theyhave heretofore heen constructed owing to variations in the heights ofbottles. But in such machines the bottles have been supported by theirbases during the capping operation. B v my present invention the hottiesare suspended by means engaging with the necks of the. bottles, and thismeai'is is constructed in proper adjustment with the cap ping:mechanism. This is possihlesince that portion ot thevhottle between itsneck and the lips against. .which sealing contactv 'is made consistsordinarily of. a double head which is molded and is quite uniform,whereas the body of the bottle is subject to variations which it hasnotI heen found possible to eliminate in manufacture.

A further object. of t-hc invention is to relieve the body of thebottle. 'from the strains imposed in capping. and thereby eliminate thedanger of breakage or weakening of the bottles thereby.

Further objects are to produce a capping- Specification of LettersPatent. Application med Augst its, isos. serial No. 512,956.

ings which form a part of this application- Figurel is side elevationwith parts at lthe side Where ,the closing is effected in verticalsection, showing a capping machine embodying my invention. Fig. 2 isa'pla'n view of the same with parts broken away.

The framework of the machine comprises an axial column 1 and a secondcolumn 2 adjoining the side where the sealing.r is effected. Thesecolumns may be comparatively short and may have their bases supported ona table since no mechanism is 'required below t-he level at. which thebottles from the machine. The axial column car; ries a rotary member 4twith a rim which carries a serieslof guides 5, 5, which are tn hesparallel with and-equidistan't from the axis of lthe rotary member.These carry capping-heads 6, 6. The Capping headsl have Vcap ing-chucks,Y, set intheir lower ends. Tie capping-headscarr'y below .the

.and carry them to the positionirhere they are closed u pon the bottles.The guards have holes in them through which the caps willpass readilywlienreduced in'diamet'er hy the operation of capping topermit theirwithdrawal with the hot-ties. The cappingheads havev a short verticalmovement and are normally heldat -the upper limit-s of their movementsby springs 9, 9. i

A fiat ring- 10 is bolted to projections ex- 'tending from the lowerside of the rim of the rotary member and is carried hy and forms a partof the rotary' member. The ring has holes opposite the capping-.headsthrough which the bottle-necks can be passed and the hottle-lipspresented to the action of the .rapping-heads. A pair of jaws` oneofiwhich l1 is made fast. to the flat ring. and the other of which 12 ismovable. is located over cach of thehoies and serves as abottle-suspending means for en` `raging the necks of bottles. The jawsare drawn together by springs 13, 13. These springs permit the' jaws tobe pushed apart by the act of inserting a bottle and snap together underthe bea-ds `which surround tt\e neck at the mouth. At the position areconvenient-ly brought "to Vand removed chucks guards 8, 8, which'support the capsA n the accompanying two sheets of draw- I released.

where the caps' are closed un the bottle the movableI jaws come oppositea roller 14 carried one-of the columns of the machine which locksthejaws. On lea-ving the side where the closing is effected the movableAjaw is pushed away from'the fixed ja'w by o n the column and the bottleis Therotary member carries a` bevel gear 16 by which it is driven inthe direction indicated byan arrow.- This gear isvengaged by 'api'nion17.0na'shaft 18 through which vpower is applied'to the'machine and which1s' carriedby bearing'slf) ,and 20 on the tops of the:columns. The'capping heads are def pressed towardthe bottle-suspending means to'eectl thef-sealinget the' side where the closigfisl-'efected by beingbroughtv under -a cam 21 which is conveniently -a roller mounted VVonthe driving shaft. Rollers Z2 23'larri'ed by the two A.columns supportthe' fiatI ring and the bottle-suspendingmeans on Ctherside where.l theclosing 'is effected.
